David Handermann commented on NIFI-12468:
-----------------------------------------
Thanks for the reply [~mosermw].
Yes, it is helpful to have this captured for future reference of potentially
similar scenarios. I adjusted the title of the issue to mention Environment
Inoperative and Stream Closed to highlight the particulars.
If this happen due to something like running out of disk space, the appropriate
action probably would be to stop NiFi and evaluate other issues.
As the Xodus implementation already handles recovery on startup, this is worth
noting as background for potential improvement if we have similar scenarios
from general usage.
> Xodus Flow Configuration History Environment Inoperative after Stream Closed

> Key: NIFI-12468
> URL: https://issues.apache.org/jira/browse/NIFI-12468
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 2.0.0-M1
> Reporter: Michael W Moser
> Priority: Minor
>
> I caused Xodus to timeout writing a transation to flow configuration history.
> Thereafter, every operation that would update flow configuration history, or
> trying to view flow configuration history, continues to throw an exception.
> The UI shows "An unexpected error has occurred. Please check the logs for
> additional details" based on a 500 response from the REST API
> /nifi-api/flow/history
> I had to restart NiFi to recover. Hopefully, this code can be improved to
> detect exceptions and recover on its own.
> I caused the initial problem by setting a breakpoint while a debugger was
> attached to NiFi. I dragged a new Process Group onto the graph from a flow
> definition file and let it sit at the breakpoint for a while.
